I have an external HD, and have created a partition I have named Super Duper clone. The other partition is Untitled. When I open SD, I get this message, attached below. Does that mean that it will delete all the info on the whole drive? That would be a disaster, as I have other stuff on that partition? Or can I safely use SD and it will only erase what's on the partition called Super Duper? Note, before I partitioned the drive, the whole drive was called G-Drive USB.
